The world's population is expected to reach eight billion this month.
The UN estimates the landmark figure will be reached next Tuesday (15th November) for the first time ever.
Seventy years ago the global headcount was estimated to be just 2.5 billion.
The world's population hit seven billion in 2011.
Earlier this year, the population of the Irish state was recorded at over 5.1 million people for the first time ever.
According to those figures from the Central Statistics Office, the counties with the highest growth were in Leinster with Longford seeing a population rise from 2016 of 14%.
In Munster, Waterford also saw above-average population increases of more than 8%.
Both Leitrim and Roscommon also had above-average rises, however, the three counties in Ulster (Cavan, Donegal and Monaghan) did not.
Between 2016 and 2022 there was an increase in population in every county.
In the past six years, there was also a net inward migration of 190,000 people.
